I. Coolant Management
1. Coolant Level and Quality Control
Check the coolant level daily and maintain it between the minimum and maximum marks.
Use deionized water or a specialized coolant (such as an ethylene glycol mixture) to prevent scale buildup.
Replace turbid or deteriorated coolant immediately. In high-temperature environments, the replacement cycle is recommended to be shortened.
2. Temperature Monitoring
Immediately shut down the machine for inspection if the return water temperature rises abnormally (approaching the alarm value).
The coolant's boiling point must be higher than the ambient operating temperature (use a high-boiling-point coolant in hot weather).
II. Circulation System Maintenance
1. Pump and Piping Inspection
Test the pump's operating status. The flow rate should be ≥1 liter per minute. 0.5 liters, any abnormalities require repair.
Check the water pipes for bends and leaks. In high-temperature environments, secure the pipes to prevent softening and deformation.
2. Cleaning the Heatsink Components
Clean the heat sink dust monthly with compressed air. Metal dust should be removed with alcohol.
Replace fan blades if deformed or making unusual noises. Lubricate the bearings regularly.
3. Seasonal Maintenance
In hot weather: Increase the frequency of coolant freezing point testing and install air conditioning in the electrical control cabinet for cooling.
In cold environments: Drain the cooling system to prevent cracking or add antifreeze.
4. Troubleshooting
Regularly clear the cooling pipes to prevent blockages and overheating. Replace the thermal grease with genuine parts to ensure efficient heat transfer.
